Profanity

There are two utterances of the expletive "fuck" and some use of swear words such as "shit", "hell", "bitch", "damn" and "ass". A chunk of which is said by a teen. Also at least four uses of God's name in vain (GD x 2; Jesus as an exclamation x2)

Frightening & Intense Scenes

In one scene, Ghidorah rises up from Rodan's volcano and delivers a terrifyingly loud roar, striking a dramatic pose as the background shows a cross and the sky is hellish. The whole concept is highly reminiscent of Satan rising from Hell in the Book of Revelation, and it can be extremely frightening and disturbing for some viewers.

This film is MUCH darker than any other "Godzilla" film so far, having the look and feel of an apocalyptic film by featuring prolonged sequences of indiscriminate wanton mass destruction and colossal collateral damage and extreme frenetic mayhem throughout, as well as religious allegories, Satanic imagery and themes, lots of brutal killings and graphic violence, plentiful amounts of ruthless action, a brutal grimdark atmosphere, and a relentlessly oppressive and nihilistic tone.

There was a scene that featured an entire group of scientists being shot dead by Charles Dance's character's madmen. The group of dead bodies were seen on the ground as Charles, Vera Farmiga, and Millie Bobbie Brown were walking past.

There was an intense scene that featured Rodan chasing several military jets in the air. One pilot decided to eject himself from the jet due to how close Rodan was to him. Once he ejected the jet, Rodan opened his mouth and swallowed the man whole.
